So, here we are with our hands-on demo video of Windows 10 Mobile Build 10586.63 on a mid-ranger Lumia 640 XL and a last-gen low-end device Lumia 525. You can read about some of the common bugs and issues faced by Insiders using this build by clicking here.
As you will see in the hands-on video, the build behaves consistently offering a smooth performance across the UI navigation and is solid as a daily driver. It is polished and even on Lumia 525 you won’t see crashes or freezes or the dreaded resuming screen. There are some minor bugs that Microsoft needs to fix, but you can live easily with this build. Battery Life has been stellar on our devices. We must mention that we haven’t done hard reset on our devices but we recommend if you are facing lots of issues.
